#9. Signal Lights (Indicator Lights)
Signal lights, also known as indicator lights or turn signals, are crucial for communicating a vehicle’s intended direction to other drivers and pedestrians. Located at the front and rear corners of the car, these blinking lights signal left or right turns, lane changes, or hazards. Emergency lights, activated by hazard light switch, blink all signal lights simultaneously to indicate vehicle breakdown or emergency situation.
#10. Roof and Pillars
The roof forms the upper enclosure of the car, protecting occupants from the elements – sun, rain, snow, and debris. Car roofs are designed for structural strength and may incorporate features like sunroofs or roof racks. Pillars are the vertical supports that connect the roof to the car’s body. They are critical for structural integrity, especially in rollover accidents. Pillars are typically designated by letters (A, B, C, and sometimes D), starting from the front of the car.
#11. Doors and Windows
Doors provide access to the car’s interior for passengers and the driver. They are designed for security, safety, and weather sealing. Car doors incorporate various components like door locks, handles, window mechanisms, and side impact beams for safety. Windows, made of glass, provide visibility and can often be lowered or raised for ventilation. The windshield, a specialized front window, is crucial for forward visibility and structural integrity.
#12. Rear Panels
Rear panels encompass the structural sections at the back of the car. This area includes the rear fenders, taillight housings, and often integrates with the bumper and trunk opening. The rear panel design contributes to the car’s overall styling and aerodynamic efficiency.
#13. Front Panels
Front panels are the body sections at the front of the car, typically surrounding the engine compartment and headlights. They include fenders, the upper grille surround, and contribute to the mounting of the hood and bumper. Front panel design significantly impacts the car’s frontal appearance and aerodynamics.
#14. Steering Wheel and Car Wheels
While the steering wheel is an interior component, it is intrinsically linked to the car’s body in terms of control and function. The steering system, including the steering wheel and column, allows the driver to control the direction of the front wheels. Car wheels, attached to the axles, are essential for movement. They are body parts in the sense they are external and fundamental to the vehicle’s operation.
#15. Front and Rear View Mirrors and Windows
Mirrors, both interior rearview and exterior side mirrors, are vital for driver awareness of the surroundings. They enhance safety by providing visibility to the rear and sides of the vehicle, minimizing blind spots. Windows, as discussed earlier, provide essential visibility and protection.
